Question

Calculate moles , no of total atoms and no of molecules in 40g NaOH .​

Answer 1

Answer:1 mol, 7.53*10^23 atoms and 6.02*10^23 molecules.

Explanation:

The number of moles = mass/molar mass.

1 mole of NaOH =40g by mass /40g by molar mass.

Which is =1.

1 mole of NaOH contains 7.53*10^23 atoms.

And,

1 mole of NaOH contains 6.02*10^23 molecules.
